Textbook 1986emand for controllability and conversion of electric energy has made this area increasingly important, which in turn has resulted in new device, circuit and control developments. In particular, new components, such as the GTO and power MOSFET, continue to extend power electronic technology to new ap

Semiconductor Switches and Power Controllers for AC,d. The current half-cycles of different polarity are carried alternately by the two thyristors. So that a continuous alternating current can flow the thyristor taking over the current must be retriggered after each current half-cycle. If the thyristor is not triggered, the alternating current is extinguished as it passes naturally through zero.

Semiconductor Switches and Power Controllers for AC,If one introduces a semiconductor switch into a single-phase ac circuits, it must be designed to carry current in both directions; for instance it could consist of two thyristors in antiparallel (see Fig. 2.2). In such a semiconductor the current begins to flow as soon as the thyristors are triggere

Externally Commutated Converters, the period of commutation. In the case of line-commutated converters the supply system is this source of ac voltage with load-commutated converters the load represents this ac voltage source. Externally commutated converters operate with natural commutation.

Self-Commutated Converters,(usually a quenching capacitor) belonging to the converter or is formed by increasing the resistance of the converter valve to be turned off (e.g. a power transistor or a thyristor capable of being turned off).
